EA-PS 9500-20 1U Programmable DC Power Supply

The EA-PS 9500-20 1U is a high-performance 3000W programmable DC power supply from the EA-PS 9000 1U series, designed for demanding laboratory, R&D, and industrial applications. It delivers a wide output voltage range of 0...500 V and a high output current of up to 20 A. Housed in a compact 1U high, 19-inch rack-mount chassis, this unit features a flexible autoranging output stage, ensuring optimal power delivery—higher voltage at lower current or higher current at lower voltage—all within the 3000W power limit. With an efficiency of up to 93% and active Power Factor Correction (PFC), it operates effectively on an AC input of 180...264 V. The power supply is equipped with comprehensive protection features including Overvoltage (OVP), Overcurrent (OCP), Overpower (OPP), and Overtemperature (OTP) protection. For versatile control, it offers galvanically isolated digital interfaces (USB and Ethernet) supporting SCPI commands and ModBus RTU protocol, plus an analog interface. Additional functionalities include remote sensing, a share bus for parallel operation to increase power, a discharge circuit for safety, and temperature-controlled fans for reliable cooling. It is an ideal solution for high-voltage electronic testing, prototype development, and industrial power applications.
